A damper of a heating, ventilation, and/or air conditioning (HVAC) system includes a damper blade having a blade body with a hollow portion extending to an end of the blade body. The damper also includes an axle defining an axis about which the damper blade is configured to rotate, where the axle extends from the end of the blade body. The damper also includes a spring thrust bearing having a spring thrust bearing opening through which the axle extends. The spring thrust bearing is configured to support an axial load of the damper blade. The damper also includes an end cap disposed within the hollow portion of the blade body such that the end cap is flush with the end of the blade body.

A mold for an injection molding tool. The mold has a pin gate extending between a gate inlet and a gate opening. The pin gate forms a tapered, cylindrical channel through a body of the mold and abruptly transitions to a smooth funnel. The gate opening is positioned at an end of the funnel. The pin gate is configured to receive molding material from a runner channel of the injection molding tool at the gate inlet and dispense the molding material at the gate opening. The mold also has a mold cavity in fluid connection with the gate opening of the pin gate and configured to receive the molding material therefrom.

The present invention relates to a plastic material for use in various application. Further, the present invention relates to a plastic material for an industrial former (herein also designated as a mold). Additionally, the present invention relates to a mold made of a plastic material and the method for the manufacture of said mold. Furthermore, the present invention relates to an industrial process using such mold, such as in a process for making rubber goods comprising dipping of a mold into a rubber emulsion, wherein the mold consisting of a plastic material having a surface tension in the range from 25 to 60 mJ/m2 measured according to ASTM standard D-2578/09.

A method of producing an in-situ molded concrete object includes positioning a form on a substrate. The form can include a leg portion, a face portion, and a frangible portion. The frangible portion can connect the leg portion to the face portion. The method includes coupling the leg portion to the substrate to create a container open on at least one side. The method also includes pouring concrete into the container. The frangible portion can be fractured to separate the face portion from the leg portion.

An instrumented mold formed by an assembly of strata includes, within the assembly of strata, a measurement structure provided with at least one pressure sensor and/or at least one temperature sensor or any other sensor capable of measuring a physical quantity, the structure typically being in the form of a flexible support housed between two strata.
